Our objective is to evaluate whether the use of guided growth with eight-plates is more effective than the use of Blount staples for the correction of the idiopathic genu varum or idiopathic genu valgum.
A systematic review (SR) was carried out according to the appropriate methodology for randomized clinical trials (RCTs). We searched seven databases through a previously defined methodology, and we included RCTs, regardless of language, period of publication and status of publication.
Resulted in 6830 articles retrieved. Of theses, we identified 14 potential eligible studies. but just one RCT was included for the SR. The included RCT compares the eight-plate and the Blount staple and showed no statistically significant difference for the outcomes of time to correct the deformity, postoperative pain after 24 hours and postoperative pain after 72 hours. The study is of low or very low level of evidence to determine the most effective technique. We didn't find a RCT that compared the correction of the genu varum.
Good quality randomized clinical trials comparing Blount staples versus eight-plaque must be performed to determine which technique is superior for coronal plane corrections.
我们的目的是评估使用八孔钢板引导生长技术矫正特发性膝内翻或特发性膝外翻是否比使用布朗钉更有效。
根据随机临床试验（RCT）的适当方法进行系统评价（SR）。我们通过预先定义的方法检索了七个数据库，纳入了RCT，无论其语言、发表时间和发表状态如何。
共检索到6830篇文章。其中，我们确定了14项潜在符合条件的研究。但纳入系统评价的RCT只有1项。纳入的RCT比较了八孔钢板和布朗钉，结果显示在矫正畸形所需时间、术后24小时疼痛和术后72小时疼痛等结果方面无统计学显著差异。该研究证据等级低或非常低，无法确定哪种技术最有效。我们未找到比较膝内翻矫正情况的RCT。
必须开展高质量的随机临床试验，比较布朗钉与八孔钢板，以确定哪种技术在冠状面矫正方面更具优势。
